Question

The area of a circular pond is 345.6 m^2. A path of width 3.5m runs all around it, on the outside. Calculate the area of the path​

Answer 1

Answer:

Area of path =  270.4 sq. meter

Step-by-step explanation:

area of circular pond = $\pi r^{2}$

345.6 = 22/7 * $r^{2}$

$r^{2}$ = 110

r = 10.5 m (approximate value after square root)

-----------------------------------------

Add width width 3.5m in radius (10.5) to find radius of outer part

radius = 3.5 + 10.5 = 14 m

now area of pound along with path = $\pi r^{2}$ = 22/7 * 14 * 14 = 616 sq. meter

------------------------

Area of path = area of pond with path - area of pond without path

Area of path = 616 - 345.6

Area of path =  270.4 sq. meter
